PUMP.

To all whom t may concern.'

Be it known that we, JESSE B. WISE and CHESTER L. WISE, citizens of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improve-l ments in Pumps; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to Amake and use the same.

This invention relates to improvements in pumps, and has for its object to provide a very simply constructed, yet extremely efficient device which can be inexpensively manufactured.

A further object is to provideV an improved casting to which any length of pipe can be connected so as to use the casting with any depth of well, the pump cylinders being adapted to connect with the upper end of the casting.

With the above and other objects in view, our invention resides in the novel features of construction, combination and arrangement of parts which will hereinafter be more particularly described and claimed.

In the accompanying drawings: Figure l is acentral vertical longitudinal section of the pump; Figs. 2 and 3 are respectively transverse sections taken on the lines 2 2 and 3 3 of Fig. l.

In Figs. 1 to 3, we have shown a double acting pump in the construction of which our improved casting 1 is used. This casting comprises a pair of upright spaced apart couplings 2 and 3, the lower ends of -which are internally threaded as shown at 4, while the upper ends thereof are externally threaded as shown at 5. The valve .casing 6, substantially elliptical in cross section, is interposed between and spaced above said couplings 2 and 3, the bottom of said casing being connected by a pair of branches 7 and 8 with the coupling members 2 and 3. These branches 7 and 8 are formed integrally with the inner sides of the couplings and with the bottom of said casing 6, thereby establishing communication between said couplings and the valve casing. The upper end of the valve casing 6 is contracted as shown at 9 and is adapted to receive an outlet pipe 10 which extends upwardly and is provided adjacent its upper end with a discharge opening 11. The valve casing 6 is also provided its Specification of Letters Patent.

Application filed November'22, 1915. Serial No. 62,795.

. jammed or otherwise interfering with one another, vwe provide an upright rod 14 which is preferably threaded into the bottom of the casing between the valve seats 12. The valves are prevented from moving upwardly to a too great extent by a horizontal retaining rod l5 which extends across the casing and is connected intermediate its ends with the upright rod 14 as shown in Figs. 1 and 3. Cylinders 16 are connected to the upper end of each of the couplings and are adapted to receive for reciprocation therein pistons 17 which are carried by the upright piston rods 18 whose upper ends are pivotally connected to an operating handle 19. This handle 19 is preferably pivotally connected at 20 to the upper end of the pipe 10 as shown. The lower ends of the couplings 2 and 3 receive the yupright pipes 21 which convey the water from the well Ato the couplings, the lower ends of said pipes 21 being threaded. to receive the upper ends of valve casings 22 which are here shown as short sections of pipes having valve seats 23 in their bottoms with which ball valves 24 are adapted to coact. The ball valves 24 are prevented from moving upwardly and out of the casing 22 because of the small diameter of the pipes 2l.

From the foregoing description, it is obvious that the casting 1 may be used no matter what the depth of the well may be because any length of pipes 21 may be used in order to convey the water from the lower portions of the well to the upper and to the casting l. It is also evident that the length of the stroke of the pistons and the length of the pump cylinders can be readily changed merely by placing ones of different lengths on the casting 1.

In operation, the handle 19 is moved up and down as in the ordinary form of pump, this causing the pistons 17 to be reciprocated to raise the Water. As the left piston rises, the valve 24 will rise, thus drawing water from the well into the left hand pipe 21. When, however, thepiston in the left hand cylinder is forced outwardly, the valve 24 will be closed and the water trapped within the pipe 21. That part of the water which has risen above the bottom of the branch 7 will be forced through said branch, past the `valve 12 and into the valve casing' 6, from whence it will be forced upwardly through the outlet pipe l() and out the discharge opening l1. During this movement of the left hand piston, the operation of the right hand piston is also drawing water upwardly from the well. It is obvious that the movements of the right hand piston are the reverse of those described for the left hand piston, that is, when the left hand piston is moving upwardly and drawing water into the pipe 21, the right hand piston is moving downwardly and forcing the water trapped within the right hand pipe 21 out through the branch 8 into the-valve casing 6.

From the above description of the construction and operation of this pump, it is evident that we have produced a very simple casting including a coupling and a valve chamber, which forms the main portion of an exceedingly simple and inexpensive pump, which can be used in any depth of well.

We claim as our invention ln a pump of the class described, including a one-piece casting comprising a pair of upright spaced cylindrical couplings externally threaded at one end and internally threaded at the other, said couplings having openings in their inner adjacent sides, a valve casing elliptical in horizontal cross section and having a flat bottom provided with a pair of spaced apart valve seats, the top of said casing being extended into a contracted cylindrical neck, said casing being interposed between and spaced above said couplings, and a pair of branch pipes surrounding the opening in said couplings and formed integrally with the latter, said pipes converging upwardly and formed integrally with the bottom of said casing, the bores of said pipes establishing communication between said casing and said couplings, pump cylinders threaded upon the upper ends of said couplings, pistons in said cylinders, means for operating said pistons, an inlet pipe threaded to the lower end of each of said couplings, valves in said inlet pipes, an outlet pipe threaded upon the contracted neck, a pair of valves coperating with the seats in said casing, an upright rod projecting from the bottom of said casing between the valve seats, and a horizontal retaining rod extending lacross the contracted top of said casing and connected to said upright rod.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
